Just to make things clearer Rockdog, you could be right, but that depends on what the pilot has selected in the Nasa software. Here is the full info for the different landing modes for the FC40.
Push both sticks to the left bottom or right bottom to start the motors. A different Cut Off Type stops the motor in a different way.
Select the option you want in the Nasa Assistant.
Immediately In any control mode, once motors start and throttle stick is over 10%, motors will stop immediately when throttle stick is back under 10% again. In this case, if you push the throttle stick over 10% within 5 seconds after motors stop, motors will re-start. If you don’t push throttle stick after motors start in 3 seconds, motors will stop automatically.
Intelligent. In any control mode, only push both sticks to the left or right bottom can stop motors. In ATTI./GPS Mode, any one of following cases will stop motors. (1)You don’t push throttle stick after motors start within 3 seconds. (2)Throttle stick under 10%, and after landing 3 seconds. (3)The slope angle of multi-rotor is over 70°, and throttle stick under 10%.
